how to get the coordinates from all parts? loop through all parts en print the coordinates

rooiejoris

Hi,

I am not a programmer, but I think I want something fairly simple:
I want a list of coordinates of all parts in the part studio.

Basically loop through all parts and print the  coordinates in the monitor (or save to csv, but that is luxury... : )

I tried chatgpt for inspiration. (see the featurestudio starting with 'chatgpt' and 'google' There are probably some hints in there, but I didn't get it to work.

Can someone give me a better hint, or a working script... : )

When you display the results of box3dCenter(), it will always be in meters since it is displaying the raw value stored by the variable coord in your example. If you display a ValueWithUnits in a custom table, it will go off of your workspace's unit settings. If you want to bypass that, you'll have to do some conversion math and display it as a string instead. 

The box3dCenter function returns a Vector, which is an array of ValueWithUnits values (x, y, z). So to display an individual value of a vector, you can call it like so

coord[0]

To display the value in your table, you can add the key/value pair onto the map when appending a row. 

rows = append(rows, tableRow({ "name" : partName, "coord" : coord, "coordx" : coord[0], "coordy": coord[1] }));

Thanks...!
Also improved my script in de mean time.
Nice to know was to divide by millimeter to 'just get the value'.

key was here:

            var xcoord = roundToPrecision(coord[0]/millimeter,3);

            var ycoord = roundToPrecision(coord[1]/millimeter,3);

Looping through parts is possible for sure, but how you define the coordinate of a part? Do you have some mate connector associated with that part or just take a center of gravity or the center of bounding box?

the onshape example works, I get a custom table
now I cant get the units to mm instead of meters

and is it easy to make a column for just X and Y? in other words how to extract the X and Y value from:

var coord = box3dCenter(evBox3d(context, {

                    "topology" : part,

                    "tight" : true

            }));

see the "onshapeexample_volumetable Copy 1" featurescript
